WARREN MGARTHUR, JB., OF CHICAGO, ILLINOIS.

TUBULAR LANTERN.

of Illinois, have invented a new and useful Improvement in TubularLanterns, ofwhich the following is a specification.

This invention relates to a tubular lantern in which the plate uponwhich the globe is mounted is hinged to the lower portion of the tubularframe and in which the globe is held in its normal position by a chimneywhich is provided at its lower end with a hinged section or collar whichbears upon the globe.

The object of this invention is to provide the hinged chimney section orcollar with convenient means for moving the same up to release the globeor down to secure the globe in position.

In the accompanying drawings: Figure l is a front elevation of a tubularlantern provided with this improvement, the lifter shaft being turneddown to hold the hinged collar and the globe in their normal position.Fig. 2 is a similar view of the upper part of the lantern, showing thelifter shaft and the collar turned up to release the globe. Fig. 3 is aside elevation, partly in section, showing the lifter shaft and thehinged collar partially turned up. Fig. 4 is a side elevation of theupper portion of a lantern, showing a modified construct-ion of the liftmechanism.

Like reference characters refer to like parts in the several figures.

10 represents the oil font, 11 the air chamber on the same, 12 thetubes, 13 the lantern top containing the air inlet chamber to which theupper ends of the tubes are connected, 14: the globe, and 15 the globeplate which is connected by a hinge 16 with the lower part of thelantern frame and provided with guards 17 or other suitable devices forattaching the globe releasably to the globe plate. All of these partsmay be of any well known or suitable construction.

18 represents the fixed section of the chimney which is secured in thelantern top in any suitable manner and provided at its lower end with anoutwardly-projecting flange 19.

20 represents the movable collar or chimney section which is connectedwith the fixed section by a hinge 21 on the front side of the lantern sothat this collar, which prefer- Specification of Letters Patent.

ably'fiares downwardly, canbe swung up or down on the opposite or rearside.

22 represents a cranked lifter shaft which is arranged across thelantern frame on the front side thereof and which extends throughsuitable openings 23 in the hinged collar or chimney section. This shaftis journaled on the tubes in bearings 24:

Q5andprovided at one end with an arm 26 for manipulating the shaft. Uponturning the shaft down, as represented in Fig. 1, the hinged collar orchimney section is pressed against the upper end of the globe,

thereby holding the latter firmly in position. Upon turning the shaft upthe collar is swung upwardly, thereby releasing the globe and allowingthe globe plate and the globe to be tilted backwardly.

The collar is provided at its upper end with an inwardly-extendingflange 27 which extends over the flange 19 at the lower end of the fixedchimney section. These flanges assist in forming a practically tightpassage for the hot gases from the globe through the hinged collar tothe fixed chimney section.

In the modified construction represented in Fig. 4:, the hinged collaris raised and lowered by a lifting lever 28 which is ournaled on one ofthe tubes and which engages with its short arm 29 in a slot 80 in thecollar. In the normal position of the globe and collar the lever restsagainst the tube on which it is journaled and engages with a spring clipor catch 31 by which it is held in position. i

I claim as my invention:

1. The combination with a lantern frame, a fixed chimney section, anannular globeholding section arranged below said fixed section, and apivotal joint supporting said globe-holding section on one side of thelantern and permitting said section to move up or down with increasingmovement to ward the opposite side of the lantern, of actuatingmechanism mounted on said lantern frame and connected with saidglobe-holding section to swing the same up or down, substantially as setforth.

2. In a lantern, the combination with a fixed chimney section and aglobe-holding chimne section connected with said fixed section by ahinge and capable of up and down movement, of a lever mechanism journaled on the lantern frame and connected with said movable section toraise and lower the same, substantially as set forth.

3. In a lantern, the combination with a fixed chimney section and aglobe-holding chimney section connected with said fixed section by ahinge and capable of up and down movement, of a cranked lifter shaftjournaled on the lantern frame and corn nected with said movablesection, substantially as set forth.

4. The combination with a tubular lantern frame, of a fixed chimneysection arranged therein, an annular globe-holding chimney sectionarranged at the lower end of said fixed section, a pivotal ointsupporting said globe-holding section on one side of the lan tern andpermitting the same to move up or down on the opposite side, a tiltingglobe plate arranged in the lower portion of the tubular frame, andactuating mechanism mounted on said frame and connected with saidglobe-holding section to swing the same up or down, substantially as setforth.

Witness my hand in the presence of two subscribing witnesses.
